Physical characteristics of matter include its mass<span>, weight, volume, and </span>density<span>. It also specifically describes its odor, shape, texture, and </span>hardness<span>. In addition, physical properties describe whether the object is a solid, a liquid, or a gas – its phase of matter at room temperature.</span>
Answer:
velocity = distance / time taken
= 200/4
= 50 m/s
is the correct answer
Answer:
Explanation:
Wave produced in string and waves produced in air are different . The only similarity is that their frequency are equal . Otherwise , no similarity . One is transverse ( on wire ) , the other is longitudinal ( air ) . Their velocities too are different .
velocity = wavelength x frequency
if frequency is constant
wavelength ∝ velocity
wavelength is proportional to velocity . Since their velocities are different , their wavelength too will be different.
Velocity=frequency/wavelength
frequency=velocity*<span>wavelength
</span>f=341*0.8
f=272.8 Hz
